Is systemd-sysvcompact needed on a pure systemd system? [SOLVED]

Hi,I fully switched my fully upgarded Arch_X86-64/KDE to systemd.The systemd Wiki tells to begin with following the instructions for a mixed system which include installing systemd-sysvcompact.In my case (see below), pacman couldn't find that package.Is this package indeed needed for a pure systemd? for what? If Y, how come pacman didn't find it.

So, is systemd-sysvcompat required? How do I we get past the "/sbin/init does not exist" error message during boot if we remove sysvcompat? It seems like systemd-sysvcompat should be a dependency for systemd (for now) because many users will have a frustrating time wondering why their system doesn't boot after they've removed a seemingly unneeded package thinking they have moved away from systemv to pure systemd. The systemd wiki article does note yet mention how to install systemd without sysvcompat.
